People are eager to throw a high price out but when it's time to sell it for these high prices you'll find there are very few to no people willing to step up and pay these prices. If you really want to find a good price on something, advertise to crap out of it and throw it on EBay with either a really high reserve so it doesn't sell ( if your only looking for value ) or put it on EBay with a low starting bid and no reserve. ( If you are trying to sell it )
It's like people want to throw out these high prices to keep others from buying it.
Do these same people go to garage sales or estate sales and see a bike for sale and tell the seller Hey your bike is worth $3,000?
